Optical USB Fingerprint Reader GNU/Linux Edition (TPE-F4500)

The TPE-F4500 fingerprint reader is a USB peripheral perfect for individual desktop users, as well as multiple users in shared environments. Where most fingerprint readers on the market lack support for GNU/Linux or offer abysmal results the TPE-F4500 fingerprint reader achieves reliable results through the use of a larger sensor and free software support. The fingerprint reader works with the primary free software fprint project, the GNOME desktop environment, and the KDE desktop environment.

To use, simply open settings and go to user settings to enroll a fingerprint for use at login and lock screen. For superior user feedback, a red “flash” indicates that a fingerprint image has been captured. Unlike with other readers there is no question as to whether or not the fingerprint reader is working or not.

We also have a demonstration video on how to utilize the fingerprint reader under Fedora/GNOME and another one for Kubuntu / KDE.

Supports Cinnamon, GNOME and the KDE Plasma desktop

Works with the standard free software package for GNU/Linux fprint

Compatible with other applications such as sudo and anything else that works with fprint

Large sensor for consistent and reliable results every time you go to login or unlock the system

Does not rely on any OS-loaded binary blobs or proprietary drivers-no risk of losing support

Most distributions using GNOME, KDE, or Cinnamon as their desktop environment are supported out of the box. For questions about a specific distribution or release not listed above please contact support to request additional information. Distributions with KDE may still require a bit of tweaking. We have documentation for Kubuntu 25.10 that also should largely be applicable to other distributions with KDE.
